Just bought this I ran it for a half hour seems o.k. so far. Wheels are cheap plastic like on a children's toy. I like the rock catcher for debris. Seems quiet. One of the isolation feet wasn't bent right so the install bolt didn't line up without force. When installing the wheels there was a burr that wasn't removed at the factory so to get the wheel shaft through I had to smack it with a wrench or file it.
Bought this generator due to southern California edison shutting down power during high winds above 40 mph. Works great so far to power my maytag freezer/refrigerator, 55in tv, and internet. I love that this package came with motor oil and wheel kit! That's why I went with the WGen3600.
